Steam tunnels

Steam Tunnels connect all the major buildings on campus. They are used to transfer the steam from the Heating Plant to the buildings during the colder months. The steam tunnels are large enough for people to crawl through, and in earlier generations of Williams students, cross campus via the tunnels was a popular past time. Currently tunnels are locked tightly and alarmed, although a few openeings may still exist.
